text: Aerobic granulation has the ability to successfully biodegrade phenol at high concentrations as high as 250 to 2500 mg L-1. This is one of the highest biodegradation of an aerobic reactor.  Another pollutant that aerobic granules can biodegrade is 4-chloroaniline. This can really impact the wastewater treatment industry because of the effectiveness of removing these compounds. Dye and hydrophobic compounds can also be used in aerobic graduation to remove pollutants as well. Heavy metal can also be removed/absorbed from industrial wastewater by the aerobic granulation.
